Compare cheap car hire in the USA with practical tips on airports, driving rules, vehicle types and prices.
The USA is one of the best countries in the world for a road trip. Distances are large, public transport is limited outside major cities, and many of the most interesting places are only accessible by car.
Whether you’re planning a Florida holiday, a West Coast road trip or exploring cities like New York and Los Angeles, hiring a car gives you the flexibility to travel on your own schedule.
Where Most People Pick Up Their Rental Car
In the USA, car hire is almost always based at major airports. Unlike many European airports, rental facilities are often located in separate car rental centres rather than directly outside the terminal.
This means:
- You may need a short shuttle bus transfer from the terminal
- Large dedicated rental buildings house multiple companies
- Pickup can take longer at busy airports
Popular entry points include Orlando Airport, Miami Airport and Los Angeles Airport.
Direct Flights from Ireland
The USA is well connected to Ireland with multiple direct routes.
- Dublin → New York, Boston, Chicago, Orlando, Los Angeles
- Shannon → New York, Boston
Flight times range from around 7 hours (East Coast) to 10–11 hours (West Coast).
Car Hire Companies in the USA
The same major brands operate across most airports, along with a few US-specific providers.
- Hertz
- Avis
- Budget
- Alamo
- Enterprise
- National
- Dollar
- Thrifty
At larger airports, all of these companies are usually located within the same rental centre.

What Type of Car Should You Choose?
The USA has wide roads and large parking spaces, so vehicle choice is less restrictive than in Europe.
- Economy cars – cheapest option, fine for city use
- Full-size cars – very common and comfortable for long distances
- Estate-style vehicles – useful for luggage on road trips
- People carriers – ideal for families and groups
In destinations like Florida, larger vehicles are especially popular due to long drives and group travel.
Driving in the USA
Driving is on the right-hand side of the road. Roads are generally wide and well maintained.
Key differences compared to Ireland and the UK:
- Automatic cars are the standard
- Fuel is significantly cheaper
- Right turns on red lights are often allowed (unless signposted)
Speed limits are posted in miles per hour and vary by state.
Where a Car is Essential
In many parts of the USA, having a car is not just convenient – it’s necessary.
- Florida – theme parks, beaches and shopping areas are spread out
- California – long coastal drives and national parks
- Southwest USA – desert landscapes and scenic routes
- National Parks – limited public transport access
Even in cities like Orlando or Los Angeles, a car is usually required.
Useful Planning Tips
Before booking, it’s worth checking a few practical details:
- Insurance is often bundled into Irish bookings – confirm what’s included
- One-way rentals are common but may include fees
- Minimum driver age is usually 21 or 25 depending on provider
